Figure 1
W-groove prepared in an asymmetric Si(111) sample to form an asymmetric inclined diffractor. α and β are the angle of asymmetry and the tilt or inclination angle, respectively. The distance between the bottoms of the twoV-grooves forming the W-groove is a = 0.8 mm. The incident and diffracted beams are also depicted. The beam diffracted at the central ridge of the W-groove is split (the splitting angle being twice the sagittal deviation δ) by the inclined surfaces of the crystal.
